Who This Is For / When to Use
Use the Split action if you want to:
Run A/B or multivariate tests inside a Workflow.
Randomly distribute contacts across multiple paths.
Compare performance of different messages or actions.
Route contacts evenly across teams or processes.
What the Split Action Does
The Split action:
Randomly assigns contacts to one path.
Uses percentage-based distribution.
Supports up to 5 paths per Split.
Assigns each contact to one permanent path.
Important behavior
Once a contact enters a path, that assignment is remembered.
If the contact re-enters the Workflow, they follow the same original path.
If you need logic-based routing (for example, order value or tags), use If/Else, not Split.
Step 1: Open or Create a Workflow
Go to Automation.
Select Workflows.
Create a new Workflow or open an existing one.
Add a trigger if one is not already present.
Step 2: Add the Split Action
Click the + icon under an existing step.
Select Add Action.
Search for Split.
Choose Split from the Internal actions list.
Step 3: Configure the Split Action
Set the Action Name (optional).
Select Distribution Type: Random Split.
Review the default two paths (50% / 50%).
Random Split assigns contacts unpredictably, similar to rolling a die.
Step 4: Customize Paths and Percentages
Rename each path to reflect its purpose.
Adjust percentage values for each path.
Click Add Path to create additional paths (up to 5).
Remove a path by clicking the X icon.
Required Rule: Percentages Must Equal 100%
All path percentages must total exactly 100%.
If the total is higher or lower, the action cannot be saved.
You must correct the values before saving.
Step 5: Save the Split Action
Review path names and percentages.
Click Save Action.
The Workflow canvas will now display multiple branches.
Viewing Split Performance (Statistics)
How to Access Split Stats
Click the Split action in the Workflow.
Open the Statistics tab.
You can see:
How many contacts entered each path.
Total distribution counts.
Enabling Stats View in the Builder
You can also view Split statistics directly on the canvas.
Enable Stats View using the left toolbar.
Review path distribution visually.
Common Use Cases
A/B Testing
Send different versions of an email or SMS to measure engagement or conversion rates.
Lead Routing
Distribute leads across sales reps or teams in defined proportions.
Campaign Optimization
Compare different follow-up strategies and refine future Workflows based on performance.
Common Issues and Fixes
Cannot save the Split action
Ensure all path percentages total 100%.
Contacts are not switching paths
This is expected behavior.
Contacts remain on their originally assigned path permanently.
Need condition-based routing
Use If/Else instead of Split.
FAQ
What does the Split action do?
